Transmitting power over distance and time (1)

Mechanical Power Transmission

• Electrical power transmission has replaced
  mechanical power transmission everywhere except
  very shortest distances. What is worth
  remembering, however, is that from the 16th
  century through the industrial revolution to the
  end of the 19th century mechanical power
  transmission was the norm even for long
  distances.
• The oldest long-distance power transmission
  technology involved systems of push-rods
  connecting waterwheels to distant mine-drainage
  and brine-well pumps. This technology survived
  into the 21st century in a handful of oilfields
  in the US, transmitting power from a central
  pumping engine to the numerous pump-jacks in the
  oil field.

• Mechanical power may be transmitted directly
  using a solid structure such as a driveshaft
  transmission gears can adjust the amount of
  torque or force vs. speed in much the same way an
  electrical transformer adjusts voltage vs
  current.
• Hydraulic systems use liquid under pressure to
  transmit power canals and hydroelectric power
  generation facilities harness natural water power
  to lift ships or generate electricity.
• Pneumatic systems use gases under pressure to
  transmit power compressed air is commonly used
  to operate pneumatic tools in factories and
  repair garages. A pneumatic wrench can be used to
  remove and install automotive tyres far more
  quickly than could be done with standard manual
  hand tools.

Importance of pulleys
Importance of pulleys

• Belt performance is enhanced by superior pulley
  performance. High quality pulleys can
  significantly increase belt life.
• Before installing pulleys, ensure that they are
• Manufactured according to relevant standards to
  help ensure optimum performance
• Equipped with taper bushes for quick and
  accurate installation
• Corrosion resistance

Taper Bushes

• Taper bushes provide an economical, easy, and
  efficient method of securing sprocket, pulleys
  and couplings to a wide range of standard metric
  and imperial dimensioned shafts of general
  commercial tolerances and finish. The taper
  surfaces on the bush and mating hub are driven
  together by high tensile screws, causing the
  split bush to be firmly contracted onto the
  shaft. The strong clamping force enables
  transmission of high torque.

PIX makes high quality belts, pulleys and bush
9

• Manufactured from grey cast iron which ensures
  consistently high quality product
• Pulley and pulley groove specification conforms
  to IS 3142 ISO 4183 standards
• Precise surface finish ensure proper grip and
  wedging
• Increased belt life reduces recurring purchase
  cost
• Accurate and precise grooves to eliminate
  slippage of belts
• Eliminates the chances of damage to the shaft,
  bearing, motor or machinery during installation
  and removal, as there is no need of hammering the
  pulleys
• No special tool is required except a hexagonal
  key
• Saves time in installation and removal of pulleys
• Highly wear resistant. Statically balanced in
  general
• Dynamic balancing of larger pulley is done on
  requirement basis

Advantages of Taper Lock Bush

• Ease of installation and removal. Reduces
  time and cost in fitting
• No need of re-boring, full range of both
  metric and imperial sizes are available
• Facilitates easy assemble / dissemble from
  pulley and other transmission parts
• Bushes are machined with standard key-ways
